The Friends of Lake Sonoma welcomes you!

The Friends of Lake Sonoma is a cadre of volunteers that supports the interpretive and educational programs managed by the U.S. Army Corps of Engineers at Lake Sonoma.  Due to federal budget shortfalls, we also provide funding to help maintain the park and keep key facilities -- including the Milt Brandt Visitors Center -- open to public access.  We welcome your help -- financially through monetary and in-kind donations or through your service as a park volunteer!
